BRUSH.

Application led May'26, 1923, Serial' No. 641,588. Renewed-August 22, 1924.

To all whom t may concern.'-

Be it known that I. WILLIAM DAVIS Rosa, a citizen O the United States of America, residing at Portland, in the county Oi' Multnomah and State of Oregon, have invented certain new and useful Improvements in Brushes, of which the following is a specification. Y'

This invention relates to improvement-s in brushes.

The Object of the invention is to provide a brush,`which when reciprocated over a surface being cleaned, rotates to distribute the wear on the bristles and insure of the whole surface being cleaned.

A further object of the invention is to provide means between the top of' the brush head and the bottom vof the head ci' the handle to prevent wear and tear on the ends of' the bristles when operating the brush.

The invention also comprehends improvements in the `details o'f construction and arrangement of parts which will be hereinafter described and particularly pointed out in the claims. f

In the accompanying drawings:

Fig. l isa perspectivev view of my im#k proved brush.

Fig. 2 isa vertical section of the saine.`

Fig. 3 is a detail view. 4 y

l indicates a circular brush" headr provided with depending bristles 2, the head being made of hard rubber. A circumferential flange 3 is formed on or; secured to the top ofthe head 1, and its inner edge is undercut as shown at 4, the flange being flush with the edge of the head andl formed of hard rubber Or the like. Supported ,on the tops of the bristles 2 is a wear plate 5, seated in a recess formed in a metal retaining plate 6, outwardly bevelled at its edge to engage under the undercut portion et of the fiance 3 I n The retaining late 1s enlarged between u D the center and circumference, and at its cen-k ter is formed an opening 7, and surrounding the upper edge of the wall of the Opening is an annular flange 8. Fitting in the Opening 7 and supported on the wear plate 5, is a disc 9, which engages under the flange tending from the disc 9 is a handle socket l0, which receives a handle ll.

The flange will Ordinarily hold the plate (i in assembled position, but to make sure that the plate will not become separated when the brush is in use, I provide screws l2 or the like to lock the plate to the head l.

IVhen the parts are assembled, the disc 9 finds a. bearing on the wear plate and in the opening 7, consequently the brush head can freely rotate when it is reciprocated over a surface being cleaned. wear platefprevents the disc wearing away the ends of the bristles, and at the same time serves as a means for spacing the plate from said bristles.

The

sult that the whole surface is subjected to an even brush action.

Because of the head l and flange being vmadeof hard rubber, it will not mar v.turniture or the like when striking the same in the reciprocation of the brush.

IVhat I claimis:

l. A brush, comprising a flat round head having an edge flange formed o'f hard rubber, the flange being undercut on its inner edge, a plate having its edge bevelled to lit under the undercut edgeot' the .icl-ange, said plate having a central recess with lan inwardly extended flange, a disc rmounted in the recess under the flange and provided with a handle receiving` device, and a wear plate between the disc and the top of the brush head.

2. A brush, comprising a flat round hea( having an edge flange formed ot hard rub bei", the flange being undercut on its inner i edge, a plate having its edge bevelled to it under the undercut edge oli` the flange. said plate having a lcentral recess with an inwardly extended flange, and a disc mounted inthe recess under the flange and provided with a handle receiving device.

In testimonv whereof I alliX my signature,

WILLIM Davis ROSE. n. 5.]
